SHARING, OF WASHINGTON, DISTRICT 0F COLUMBIA, ASSIGNOR 0F ONE- FOURTH TO GUSTAV ESCHER, OF WASHINGTON, DISTRICT F COLUMBIA, AND ONE- FIFTH TO HERMAN .R. KUEHNER, OF LAUREL SPRINGS, NEW JERSEY WATER cLosEr Application led November` 6, 1930. Serial No. 493,867.

provide a water closet comprisinga bowl and an integral tank at the rear thereof, and wherein a relatively large water chamber eX- tends from the tank around the wall of the bowl, so that the necessary six gallons of water may be held but, at the same time, the tank may be relatively small and occupy but little additional space to the rear of the bowl.

Still another object of the invent-ion is to provide a water closet wherein the bowl has a peripheral rim which is provided with two small passageways, one for air and the other for water, and to provide mechanism whereby when the seat is occupied a small amount of water will flow from the peripheral passageway in the rim down the sides of the central well or central portion of the bowl to wash the same and, at the same time, a vacuum will be caused in the second passageway in the rim to draw out the air or odors from the bowl, which will then be passed on out through a waste pipe..

Still another object of the invention is to provide a water closet comprising a combined tank and bowl wherein the water will surround the bowl to thus lessen the size of the tank and, at the same time, toalso provide means for slightly washing the bowl during the time that the. seat is depressed and to automatically cause the air to be drawn from the bowll by a vacuum caused by a small jet of water extending across a passageway leading to the rim of the bowl.

Still another object of the invention is to provide a closet with a combined integral tank wherein there is no danger of flooding should the bowl become clogged up, as the normal height of the water in the tank and around thebowl is below the upper surface of the bowl and the'main supply will cut olf when the normal water level height is reached.

Still another object of the invention is to provide a water closet wherein the tank might be said to extend completely around the bowl and thus occupy a minimum space and to provide means whereby should the water fail to cut off, it will pass out through an overflow and down through the gooseneck of the bowl and thus prevent any looding on the floor. Still another object of the invention is to provide a water closet comprising a bowl and integral tank that will occupy but little space and, at the same time, may'be easily and conveniently cast.

Still another object of the invention is to provide a ,water closet wherein the ordinary flushing means are used but with the addition f of means for continuously washing out the bowl while the same is being used and, at the same time, to automatically vent the bowl.

With these and other objects in View, the invention consists in certain new and' novel arrangements and combination of parts, as will be hereinafter more fully described and pointed out in the claims.

Referring now to the several views showing. a preferred embodiment,

Fig. l is a top plan view of the improved water closet, parts being broken away for the sake of clearness of illustration;

Fig. 2 is a sectional view taken on the line 2 2 of Fig. l, looking in the direction of the arrows, parts being left out oi the tank for the sake of clearness of illustration;

Fig. 3 is a sectional view taken on the line 3-3 of F ig. l and looking in the direction of the arrows; v

Fig. 4 is a' vertical sectional view taken on the line 4 4 of Fig. 2, looking in .the direction of the arrows' Fig. 5 is an enlarged detailfragmentary section taken on the line 5 5 of Fig. l.

Referring now more particularly to the several views and first describing the bowl and tank rather than the mechanism contained therein, there will be seen the improved ywater closet, which comprises the bowl and,

' tinued, as at 3, and widened outslightly, as

at 4, to merge with the flat sides 5 of the tank 2. The rear portion of the tank, therefore'guis substantially rectangular, and it will be seen lthat it isof relatively narrow width; This is .c possible, because around the well or central Y' .,5'chambler or depression 6, there is thel .water i chamber 7, so that the water from the tank will extend inthis chamber complelely-'around the said welle.l

-thewell extends down into the same to forma wardlyand then doivvnwartllyv through the 'same and'out through the main'discharge 11.

As also ,mayv beseen in Fig. 2, there ist-he y main outlet 12 from thetank 2', which regis f ters with/,the passageway-13 beneathjftlie tank,

Y which passageway, of course, extends-finto the place. y

trap of the well, so that when thef'closet is flushed, the water'` will pass dowfn into 4the trapl and the usual'siphonic actionwill take By providing the water chamber T-[about the well, the tank 2 may be reduced in size,

as it is only necessary to hold six gallons of. water -to flush a water closet and, as willfbe seen, this water chamber 7 really forms part of the tankv 2. To the rear of the tank may be built the small overflow passageway 14,?"- i and 1s connected to a valve 35,wh1ch may be Y- that should the main Valve break, the-Water,

which registers with the passageway fso after reaching the top of the tank, will over- Iflow through this passfageway. and out dotted lines in Fig. 1 and insection in Fig. 3,'v

there is a small compartment 15 with an opening 16 near its top and the opening 17 at its bottom that registers with' the ltanki' There is also a vent pipe 18 connected therewith, as it is in front of this compartment that there is a vacuum formedto draw off the odors and the air from the bowl, as will be later described.

The top of the tank may have a cover 19 which, in this instance, is shown as triangularly-shaped, which gives a pleasing appearance to the closet.

Now referring to an important-part of the invention, there will be seen an integral peripheral rim 2O extending around the well of the bowl, substantially circular in. outline and divided by a peripherally extending inner wall 21, so that there are reallyy two passageways 22 and 23 formed. The passageway 23 is for drawing out the air from about the bowl and there are a' plurality of small openings 24 around its lower edge. In the same way, there are a plurali'y ofsmall holes 25 in the passageway 22, so that when water is'allowed to flow iii kthis passageway, it will, in turn, run down from the rim and wash or lubricate the well. The connections and meal for doing this will be shortly described.

The combined bowl and tank may be cast tenaces trap 8, and the wall 9ofy in the-one piece maybe cored in the base,

as; shown, .to rlighten the same, no diiicnlties v being presented in cas'tmg over the ordinary' form of closet.

" .Having thus described the bowl, the mechanism for causing the air and washing passageways-to function, as well as the "flushing arrangement, will now be described.

lThere is the main inlet water supply 26 (see Fig. 3) with a ,cut-oit' valve 27 at its top,

lthe. iioat 28 being connected to the rod 29 that extends to the valve 27. Any form of cut-olf valve and loatpmay be utilized and I have simply shown one of the standard makes.

l There is also shown the ordinary discharge valve 30 with its stem 31,'which is operated by fthe lever 32 when the small handle 33 is operated. This, too, is of standard construction.

Now, to vent and wash'this specially constructed bowl, I employ generally a mechais a-small pipe 34 with a nozzle 35 thereon that is directly opposite the openings'lt in the ,compartment 15 but spaced a slight way therefrom. The pipe 34extends' diagonally clearly seen in Fig. 2. This Valve has a ball 36 therein, whichis operated .by the stem 37,

which is spring-pressed, as at 38. The stem has a small nipple or top 39 thereon, which bears against the under side of the seat 40 and, asshownzi'n Fig. 2, the valve is normally held in its closed position.

Also 'connectedto this valve 35 is the inlet pipe 41 that extends rearwardly and is connec'ted to the main inlet 26. Thus, when the seat;40 is-'depressed and the valve is actuated, wate'iwill flow from the main inlet pipe 26 in through this j by-pass 41, and the Valve 35 now being open the water will pass upwardly and through the pipe 34 and out the nozzle 35 to spray into the small compartment 15 in the tank. i

It is to be mentioned here also that there is a small T 42 that leads from the pipe 34 Referring for the moment to Figs. 1 and 5,

there willbe seen apjipe or passageway 43 thatv has its opening, as at 44', right opposite 4the nozzle 35 and this passageway 43 extends across the outer peripheral passageway 22.

of the water in the tank running back through the passageway 43 into the peripheral passage-way 23.

Thus, it will be seen that when the seat 40 is depressed, the valve 35 is opened and not only will water be passed into the peripheral pas-v central well upthrough the openings 24 and out through the peripheral passageway 23 to thus ventilate the' closet. The water, in turn, from the spray will fall back into the tank and the gases or air will pass from the small chamber 15 up and out the vent pipe 18, which lis shown as a swinging pipe, so that it may be conveniently connected to the ordinary vent pipeconnected to all closets.

From the foregoing, it'will be seen that I have constructed a water closet wherein the tank and bowl are integral parts and wherein the tank extends around the bowl to thus provide a maximum capacity of the bowl and a minimum-sized tank. It will also be seen vthat I have formed a peripheralrim in which there are two peripheral passageways, so that all the time the seat is being depressed, a small amount of vwater will trickle down the sides of the bowl to wash the same and,

at the same time, there is automatically created a vacuum in the rim to draw off the air and odors from the bowl.

The flushing of the bowl is done in the ordinary way and all of the water in the L tank andabout the bowl will drain into the overiiow onto the floor, as the ball valve willtrap when the closet is flushed. r Lastly, it will be seen that even should the trap become stopped up, the water will not operate when the tank is lilled and the water level is below the top of the rim of the bowl.

I have found in actual use that the water used to create the vacuum and lubricate the bowl will not be over a. gallon in twenty minutes, so that although the desired functions are performed as outlined, the amount of water utilized is very small.

' and slightly wider than said bowl and communicating with a water chamber complete-l ly surroundin the well of the bowl, a hinged I- seat over the owl, a trap beneath said well and water chamber provided with an outlet, an overflow communicating passageway between said trap and the upper portion of the tank below the upper edge of the bowl, a flush valve in the bottom of the tank communicating with said passageway to the trap, a peripheral rim about the well of the bowl provided with two non-communicating passageways, said passageways provided with small outlets to the well of the bowl, one of said passageways adapted to liberate water around the well of the bowl to wash the same, the other ofsaid passageways adapted to withdraw the air from within the bowl, and a seat-operated valve adapted to liberate water to said water passageway and simultaneously eil'ect a suction on the other passageway for withdrawing air from the bowl therethrough.
